Increasing this factor generally increases the rate of reaction because particles move faster and collide more frequently.

What is temperature? 

100

In this form of carbon, each atom forms four covalent bonds with other carbon atoms, resulting in a very hard substance with a high melting point.

What is Diamond? 

100

This type of bonding involves the transfer of electrons from a metal to a non-metal.

What is Ionic Bonding? 

100

The force between positive and negative particles. ( I swear to god...) 

What is electrostatic attraction? 

100

Carbon dioxide, methane, water vapour 

What is greenhouse gases? 

200

Adding this to a reaction lowers the activation energy and increases the rate of reaction without being chemically changed.

What is a catalyst?
200

This form of carbon consists of layers of hexagonal rings with delocalized electrons, making it a good conductor of electricity.

What is graphite

200

In this type of bonding, atoms share pairs of electrons.

What is covalent bonding? 

200

the force between simple molecules- low melting points. 

What is intermolecular forces? 

200

This gas makes up about 20% of the Earth's atmosphere.

What is oxygen?

300

This theory explains how chemical reactions occur and why rates of reaction differ.

What is collision theory? 

300

A single layer of graphite is known by this name and has unique properties useful in electronics.

What is graphene?

300

This type of bonding involves the sharing of delocalized electrons among metal atoms.

What is metallic bonding

300

Metals slide over each other they are blank and blank

what is malleable and ductile?

300

What is the most abundant gas in the Earth's Modern Atmosphere. 

What is Nitrogen?

400

This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change.

What is Le Chatelier's Principle? 

400

This type of diagram can represent the electron transfer during the formation of an ionic compound.

What is dot and cross diagrams? 

400

Bonding occurring in CuO

What is Ionic bonding? 
400
Why structures like diamond and graphite have high melting points. 

What is giant covalent bonding? 

400

The Earth's early atmosphere is similar to which planet?

What is Mars

500

In a reversible reaction, these conditions are reached when the forward and reverse reactions occur at the same rate.

What is dynamic equilibrium?

500

These cylindrical fullerenes have high length-to-diameter ratios and are useful in nanotechnology.

What is carbon nanotubes?

500

Bonding occurring in H2O

What is covalent bonding 

500

Metals have strong boiling points because of the electrostatic attraction between these 2 types of particles.

What is positive ion and delocalised electron? 

500

Diesel and carbon particulates promote this environmental phenomenon 

What is global dimming?
